//! Path tracking types for JSON deserialization error diagnostics.
//!
//! This module defines types for tracking the path through a JSON structure
//! during deserialization, which enables accurate error reporting.

/// Placeholder type for tracking JSON paths during deserialization.
///
/// This type will be fully implemented in Phase 3 with breadcrumb-style
/// path tracking. Currently it's a minimal placeholder that allows the project
/// to compile.
#[derive(Debug, Default)]
#[allow(dead_code)]
pub struct PathStack;

impl PathStack {
    /// Create a new empty PathStack.
    #[allow(dead_code)]
    pub fn new() -> Self {
        PathStack
    }
}

mod tests {
    use super::*;

    #[test]
    fn path_stack_can_be_created() {
        let stack = PathStack::new();
        let _ = stack; // Suppress unused warning
    }

    #[test]
